This paper presents results of the measurement and modelling of reset noise in charge-detection circuits of detector array multiplexers at low temperatures. To explain the temperature dependence of reset noise, it is proposed to take into account the source of noise associated with emission of electrons from interface states under the gate of reset transistor. It was found that at very low temp...

The reset noise sampling feedforward (RNSF) technique is proposed in this paper to reduce the floor of readout circuit for micro-electromechanically systems (MEMS) capacitive accelerometer. Because technology-imposed size restriction on sensing element, capacitance and variation are reduced femto-farad level. As a result, from parasitic capacitance, which pico-farad level, becomes significant. ...

this article presents a new subspace-based technique for reducing the noise ofsignals in time-series. in the proposed approach, the signal is initially representedas a data matrix. then using singular value decomposition (svd), noisy datamatrix is divided into signal subspace and noise subspace. in this subspace division,each derivative of the singular values with respect to rank order is used ...
